HSS TiN step drill with drilling diameter from 4 to 52 mm. Intended for drilling in non-ferrous metals, steel sheets and plastics.

The drill is made of high-speed steel HSS and is coated with TiN (titanium nitride).

Drills coated with a TiN layer are particularly intended for machining of difficult-to-cut materials. The application of the TiN coating results in a increase in drill hardness, allows accelerating the cutting process and helps achieve better quality of the machined parts. The titanium nitride layer, by reducing the friction force, reduces wear of the cutting edge, which in turn extends the tool life.

The drill is packed in a plastic container with a hole for hanging on a hook.
